ABSTRACT:
This invention relates to a gas-assisted vaporization process for purifying cyclic esters such as glycolide, lactides and mixtures thereof which enables the cyclic ester to be rapidly separated from its impurities as a vapor component of a gas stream. The process includes a solvent-scrubbing step for recovering the cyclic ester from the gas stream.
